PRISMS: Phenomena & Representation for Instruction of Science in Middle School

Rate This Resource
This is a representation reviewed for the following learning goal:

The water falling on land collects in rivers and lakes, soil, and porous layers of rock, and much of it flows back into the oceans.

Summary

The time span of 5:25 to 5:40 of this six minute animation describes through a diagram and narration the process of water seeping down through soil and cracks in rock and eventually flowing into streams, lakes and oceans. It addresses the key idea that water falling on land collects in soil, and porous layers of rock, and much of it flows back into the oceans, and is likely to be comprehensible to middle school students.

Limitations:
While the narration is accurate, the visual component relies only on a series of photographs of soil, a cave and a rivulet of water flowing through a crack in the rock.  Additional information is needed to show the movement of water through the tiny pores in soil or cracks in rocks.

Suggestions to improve effectiveness:
Discuss with students ways surface water moves as it seeps into tiny pores in soil and cracks in rocks. Ask students to create their own diagram.

Detailed Review

Description

The representation features a detailed six minute animated lesson about the major processes that move water between land, the ocean and the atmosphere, and convert water between states. A short section, (5:25-5:40 beginning with image of porous soil to narration “along the way”), focuses on the seeping of surface water through soil and cracks in rock.

Notes for Teachers

Quality of instructional support

Does the representation accurately represent relevant aspects of the learning goal and/or brings out limitations that are not accurate?

Yes—The representation accurately represents relevant aspects of the learning goal and brings out inaccuracies, if there are any.

The representation's narration is accurate in its depiction of groundwater seeping through soil and rock, eventually reaching lakes, streams and the ocean.

Is the representation likely to be comprehensible to students?

Partial—The representation might make the learning goal comprehensible to students.

While the narration is accurate, the visual component relies only on a series of photographs of soil, a cave and a rivulet of water flowing through a crack in the rock. Additional information is needed to show the movement of water through the tiny pores in soil or cracks in rocks.

Does the representation make clear which aspects of the real thing are represented and which are not?

Partial—The representation usually, but not always, makes clear which aspects of the real thing are represented and which are not.

It is not clearly stated in this resource what aspects of this representation are real.
